STRIP-SERVING DEVICE. 7

Specification of. Letters Patent. Patented Dec. 19, 1911.

Application filed December 16, 1909. Serial No. 533,338.'

To all whom it may concern:

Be it known that I, STEWART WARING, a citizen of the United States, residing at Evanston', in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Strip-Serving Devices, of which the following is a specification.

It has been the custom among manufacturers of wall paper to market the rolls of paper with the outer end of the web loose. In handling the rolls, the paper has often become partially unrolled, andvarious other disadvantages have resulted from the practice of leaving the end of the web unattached. Eflorts have been made to secure the end of the web to the roll by meansof a gummed label or sticker applied by hand, but such efforts have always been. discontinued, chiefly because the rolls become soiled through the inevit-ablesoiling of the operatives hands.

I have devised a machine for facilitating the securing of the outer ends of rolled wall paper by means of sections ofglummed tape,

which machine may be rap ly operated, and without soiling the rolls. An incidental is that the sections of the paper or to convey any other desired information.

I will describe my invention as embodied in a machine of the character referred to, although it will be understood'that the invention is susceptible of various other uses. In the accompanying drawings, Figure 1 is a top plan view of a machine embodying the features of my invention. Fig. 9. is a side elevation thereof. Fig. 3 is a detail view of certain cams for operating a knife comprised in the machine. ,Fig. 4 is a frag mental longitudinal vertical central section.

Fig. 5 is a fragmental top plan view. Fig." (i is a detail view illustrating the moistening apparatus. Fig. 7 is a top plan and Fig. 8 is a side elevation of various cams and the parts actuated thereby. Fig. 9 is a detail view of themovable knife.

The embodiment herein shown of my invention comprises means for supporting a roll of gummed tape, means for cutting off a section of tape, means for moistening the severed section, and means for presenting said section, with its gummed and moistened .base, t e forward en face uppermost, at a point where the oper- 'ator can conveniently lay a roll of paper or other article on said section, and without handling the latter.-

The mechanisms of the machine may be supported upon a framework of any suitable construction, said framework, in this instance, comprising a 'base 1. Upon the forward end of the base is a table 2 having a recess 3 in its rear edge. Upon the rear end of the base 1 is a reel of any suitable construction, as, for example, a spool 4 rotatably supported in brackets 5. The spool has wound thereon a quantity of tape, which in this instance is gummed upon one side. A slide 6 is arranged to be reciprocated between the table 2 and the reel, said slide, in this instance, being mounted upon two parallel rails 7 fixed to the base. 1. See Fig.6. Upon the lower side of the slide 6 are out wardly extending flanges 8 which are mounted within the bent flanges of the rails 7. Forwardly of the reel is a chute 9 fixed at its rear end upon a cross bar 10 (Fig. 4.) extendin between two osts 11 fixed upon the d of said chute resting upon the slide 6. On the rear portion of saidslide is fixeda rail 12 upon which the forward end of the chute rests at times. The web extends from the reel into and through the chute with its gummed side uppermost, and is confined in said chute'by a cover plate 13 fixed near its rear end to a bar 14, said bar being pivotally supported in the posts -11 Upon one end of the bar 14 is fixed an arm 15. A coiled spring 16 extending between the free end of said arm and a fixed point upon the frame of the machine, holds the cover late yieldingly against the web lying within the chute. The length of travel of the slide 6 is such that when the slide is in its rearward posithe upper end of an arm 18 pivoted in the slide. In the embodiment herein illustrated, said clamping jaw is actuated and the slide reciprocated by a single means, which means, in this instance, is manually operated.

1 free end of the web between itself and the tape. Means provided for actuating'tlie cam plates 37'a'nd 38 fixed uponthe base l end of which lever is connected by means of j a link.2 2 to the'mid portion of an arm23 I which is pivoted at 24 to the bracket 25 fixed to the base. One end of said arm is connected by means of a link 28 to the lower end of the arm 18. If desired, the point of connection between the link 22 and the arm 23 may be made adjustable, as by providing a plurality of openings 26 each adapted to receive the pivot 27. A coiled spring 29 extending between the lower end of the arm 18 and a fixed point upon the slide 6 tends to swing said arm \in the direction to open the clamping jaw 17. 'Whenever the hand lever 21 is released by the operator, the spring 29 rocks the arm 18 and opens the clamping jaw 17. A slot 30 (Figs. 4 and 6) is provided .in the base 1, through which slot the arm 18 extends.

31 is a stop on the slide 6 to limit the The rearward travel of the slide 6 is limited by any suitable means, as an adjustable stop 32 (Fig. 4). In this embodiment the forward limit of movement of the slide is determined by the contact of the arm 18 with the forward end wall of the slot 30, but obviously any other suitable stop means maybe employed, v I

Assuming the hand lever to have been swung rearwardl yq when the operator grasps the handle and draws it toward hnn': 1 self, the slide 6 will be moved rearwardly until the rear end thereof strikes the stop 32, bringing the clamping. jaw 17 near the free end of the web, When the operator swings the hand .lever rearwardl y, the clamping jaw 17 is-first closed, pinchlng the upper surface of the slide, and then the slide; is advanced until the forward portion of the 3 slide enters the recess 3 in the table The means herein shown for severing the; web to provide a.section of suitable length; consists of a knife 33 (Fig. 9) secured to; the forward end of two arms 34, said arms: being pivotally mounted upon a pin 35 carried by said slide. A transverse opening '36 descends upon the completion of. a cutting movement- Fixedto the slide 6 a eta-5 tionary knife .or shear blade 33 coacting: with the movable knife 33in cuttingthe knife to sever the web after a sufficient por-. tion thereof has been drawn out of the chute, by the clamping j aw 17 .in the forwardf movementof the slide. Said knife-actuat-I ing means, in this instance, comprises-two at theside of the path of movement of the slide. Upon one of the arms 34 is mounted a roller 39 adaptedto move through the space between the cam plates 37 and 38 and over the upper side of the cam plate 37.

cam plates 37 and 38, a spring 42 yieldingly 55performs a similar function. When the depressed. onto "the severe the arm 51 I hold the moistening belt out oft-he path of an arm 60 Upon the rearward movement of the slide 6 the roller 39 is directed over the cam plate 37 by means of aswitch cam 40 pivoted at 41 in position to close the space between the holding said switch in the position just referred to; When the slide 6 moves-forward,

the roller 39 travels through the space between the cam plates, the knife 33 being depressed into the o ehing 36 at the proper moment to severt e web." In its forwardmovement the roller raises the switch cam, but upon the return movement of the slide the. roller'is directed by the switch cam onto the upper surface of the cam plate 37, dropping thence onto the rear portion of the cam plate 38. As the slide 6 moves forward, the

severed section of tape is drawn beneath a suitable means formoistening the gum upon the sect-ion. In this instance, the moistening means comprises an endless belt 43 of felt or other suitable absorbent material, said belt I running over pulleys 44, 45 and 46. The pulley 44 is carried upon a bracket 47 (Fig. 6) fixed to the base 1 and lies within a pan 48 containing water. The idler's 45 are mounted upon a bracket 49 fixed to the base. The idler 46 is attached to the angular po ion 1 50 of an arm 51 which is pivoted at 52 to the machine frame. The arm portion 50 extends transversely of the path of move ment of the slide 6, and is arranged to support a art of. the lower: run of the moistening elt above the path of movearent of the slide. 53 is a backing plate fixed to the angular arm-portion .50 and overlying the lower run ofsaid belt.

Thearm 51 is'rocked to depress 'the'belt onto -the section of tape, and to raise it therefrom, by m'eans ofa'plate 54 having cam surfaces 55, 56 and 57 thereon, said platebeingfixed to the side of the slide-6. See Fig.8. Afpr'ojection 58 fixed upon'the 'a'rm 51 is held 'injcontact with said cam surfaces by a coiled spring 59. When the slide is in its forward position the cam surface 57 holds the arm 51 elevated, and when the slide is in its rearmost position the cam slide is moving forward the projection 58 follows the contour of 'the cam surfaces 55,

56 and 57,'thereb,'y causing the belt to be section at the proper time, and raised. On the return or rearward movement of the slide, however, the clamping jaw 17 isopen, and therefore must remain elevated so as to movement of the clamping jaw. 'The means herein shown to attain this result comprises (Fig. 7 )pivoted at 61 upon the underside of the arm 51 and -carrying at its free end a projection which is adapted 'to ride upon" the upper side i edge of a cam strip- '63 fixed to the cam plate 130 and 1 the outer 54. A spring 64 tends'to swing the arm 60 so as to holdits free endin contact with the cam strip 63. When the slide 6 begins its forward movement the projection 58 is supported upon the cam surface 55, and

before said cam projection reaches the declivity leading from the surface 55 to the surface 56, the surface 65 of the side edge of the cam strip 63 engages the projection 62 and rocks the arm 60 so that the latter lies at the side of the cam strip. As the slide continues its forward movement, the spring 59 draws the projection 58 down the declivity leading to the cam surface 56, thereby depressing the belt onto the severed section of tape. As the slide approaches its forward position the projection 58 rides up onto the cam surface 57, thereby raising the belt-carrying arm 51 and with it the arm 60 until the projection 62 on said arm 60 is above the cam strip 63, when the spring 64 rocks said arm 60 to place said projection directly behind the beveled rear end of said cam strip. 'When the slide moves rearwardly, the projection 62 rides up onto the upper surface of the cam strip 63, thereby supporting the belt-carrying arm 51 upon said cam strip and preventing the spring 59 from depressing said belt-carrying arm. When the slide nears its rearward position, the cam strip 63 moves out from under the projection 62, whereupon the projection 58 drops onto the surface 55.

The means herein shown for moving the moistening belt 43 comprises a ratchet wheel 66 (Fig. 6) fixed to the side of the pulley 44, and a pawl 67 arranged to engage the teeth of said ratchet wheel and pivoted at 68 upon 4 a slide 69 mounted upon a plate 70 fixed to movement of the slide 6. When the slide 6 is moved the slide 69 is reciprocated by the cams 72 73 and the spring 74.

If desired, descriptive matter may be printed upon the ungummed side of 'the tape. I have herein shown a form roller 7 5 (Fig' 2) rotatably supported in suitable bearings upon the base of the machlne; an inking roller 76 also rotatably supported -1n suitable bearings just below the form roller; and an impression roller 77 for holding the tape in contact with the form. Said in; pression roller is rotatably mounted on arms .78 fixedupon a rock shaft 79, said shaft being supported in the posts 11. iinysuitable means may be provided for yleldlngly holding the impression roller agalnstthe tape, as, for example, an arm 80 fixed upon one end of the rock shaft 79, a sprmg 81 In this instance,

exerting its force upon said arm and a spring 82 tending to draw one of the arms 78 downward, Vhen the tape is moved by the clamping jaw 17, the rollers 76 77 are rotated, and an impression is made uponthe under side of the tape.

At a suitable place, as upon the table 2 in front of the recess3 is located means for absorbing superfluous moisture from the label, as, for example, a pad 83 of feltor blotting paper.

Assuming a roll of tape to be in place in the machine with the free end of the tape threaded between the form roller 75 and the impression roller 77 and through the chute 9, and further assuming that the slide is in its rearmost position, as shown in cam plates 37 and 38 between which the roller 39 travels causes the knife 33 to be depressed, thereby severing a section of the tape. The movement of the web thereupon ceases, the slide continuing its forward movement with the severed section or label lying upon the forward portion of the slide. Just as the label reaches the moistening belt 43 said belt is depressed onto said label, and remains depressed until the label has passed, whereby the gum upon the upper side of the label is moistened. When the slide 6 reaches its forward position, the forward portion thereof lies within the recess 3 with the label lying on the slide with its gummed v 'together,-and presses said article upon the label then laying the roll upon the table in such position that the label'lies' upon the absorbent pad 83, the operator rolls the article to and'fro until all parts of the label have been pressed against the roll and any surplus water expressed from beneath he label, such surplus moisture being absorbed by the pad 83.

It will be seen that the machine is capable of rapidly forming gummed labels, moistening them and presenting them in such place and position that they may be used without handling, thereby preventing soiling of the operatives hands and consequent soiling of the articles operated upon.

The foregoing detailed description of the present embodiment and its special use is not to be understood as an undue limitation of the invention.
